Pump cover air tightness detection device

Abstract

The invention discloses a pump cover air tightness detection device which is characterized by comprising a pump cover sealing structure; wherein the pump cover sealing structure comprises a bottom plate, a sealing base is arranged on the bottom plate, a connecting end face of the lower portion of a pump cover is tightly attached to the top face of the sealing base, and a sealing ring is arranged on the connecting end face of the pump cover; a pressing mechanism is arranged on the bottom plate; a plugging head is arranged at a pump outlet of the pump cover, and a supporting column is further arranged in the direction right opposite to the plugging head. A gas receiving end cover is arranged at a port of the top face of the pump cover, an annular sealing ring is arranged between the gas receiving end cover and the contact face of the pump cover, a bolt is arranged on the gas receiving end cover and matched with a threaded hole in the sealing base so that the gas receiving end cover can be tensioned, and a gas nozzle used for being connected with a gas pipe is further arranged on the gas receiving end cover. The air leakage detection device has the advantages of being simple in structure, low in manufacturing cost, good in sealing effect, high in detection efficiency and suitable for air leakage detection of small-scale machining.

Description

technical field [0001] The invention relates to the field of pump cover leak detection structure, in particular to a pump cover air tightness detection device. Background technique [0002] The water pump pump cover is an important part of the water pump, so the water pump is required to withstand pressure and not leak. Therefore, after the pump cover is machined, it is necessary to test the air tightness. The air tightness test is mainly to detect whether there are trachoma on the pump cover, so as to reflect whether the water leaks during the later use of the pump. The existing practice is to test air tightness on special air tightness testing equipment. For small batch production, the cost of introducing air tightness testing equipment is high, which is not conducive to controlling production costs. In addition, through air tightness The efficiency of testing equipment to detect the airtightness of the pump cover is low, which is not conducive to improving production eff...
